The KPIs Every New Trades Business Owner Should Track in Australia
When you buy a trades business in Australia, the key performance indicators that matter most are job gross margin, average revenue per job, quoting conversion rate, outstanding debtors, and cash on hand — tracked weekly in the first 90 days, then monthly once you know what normal looks like. These aren't complicated metrics. Most of them live in your job management software already. The challenge isn't finding the numbers; it's knowing which ones to pay attention to when everything feels new and slightly chaotic.
Most first-time owners inherit a business where the previous operator knew what "normal" felt like. You don't have that yet. KPIs are how you build that baseline quickly — and how you catch problems before they become expensive.
This is Module 8 territory from the Playbook: the first 90 days are about getting visibility and getting stable, not transforming everything at once.
Start here: the five metrics that tell you whether the business is healthy
Before you optimise anything, you need to know what you actually bought. Here are the five numbers to get sorted in week one.
1. Job gross margin
Job gross margin is your revenue from a job minus the direct costs of doing that job — labour, materials, subcontractors. Express it as a percentage.
For most Australian trades businesses, a healthy job gross margin sits between 40% and 60%. Plumbing and electrical tend to run a bit higher because labour is specialist and priced accordingly. Landscaping and cleaning typically sit at the lower end because the work is more competitive and materials costs vary. If your job gross margin is under 30%, you're either underquoting, over-staffed for the work you're doing, or buying materials at retail (which means someone hasn't set up supplier accounts properly).
2. Average revenue per job
Total revenue divided by number of jobs completed in the period. Simple, and very useful.
A rising average revenue per job usually means you're getting better at upselling or doing more complex work. A falling average might mean you're filling the schedule with smaller, lower-value jobs to keep busy — which feels productive but often isn't. One trades business owner I spoke to had an average job value of $380 but a competitor in the same suburb was averaging $650 doing similar work; the difference came down entirely to how quotes were structured.
3. Quoting conversion rate
How many quotes you send that turn into paid jobs. If you're quoting 20 jobs a week and winning 12, that's a 60% conversion rate.
Trades businesses typically convert between 40% and 70% of quotes, depending on whether they're doing reactive work (emergency plumbing, broken air con) or planned work (landscaping, renovations). A falling conversion rate can mean your pricing is drifting too high, or that you're quoting jobs you shouldn't be competing for. A rate above 80% can mean you're too cheap.
4. Outstanding debtors (aged receivables)
How much money is owed to you and how old the invoices are. Break it down: under 30 days, 30–60 days, over 60 days.
The over-60-days bucket is where bad debts live. Check this every week in the first 90 days. Incoming owners often discover that the previous owner had let a few accounts run because they didn't want the awkward conversation — and now you're the one who has to have it (which is fine, you're the new owner, nobody's upset with you personally).
5. Cash on hand versus monthly fixed costs
How many months of operating expenses you have in the bank. Aim for at least six to eight weeks of cover. Trades businesses are cyclical — slow periods happen — and you want to know well in advance if things are getting tight, not the week before payroll is due.
The KPIs to add once you've got the basics sorted
Once you've got those five under control — usually by the end of month two — you can layer in a few more useful metrics.
Labour efficiency
Billable hours divided by total hours paid. If you're paying a technician for 38 hours a week but only billing out 28 hours of actual work, your labour efficiency is 74%. That missing 10 hours is drive time, admin, waiting around, or jobs that ran over estimate. The industry benchmark varies, but anything above 80% is solid for most trades.
Materials as a percentage of revenue
Track this over time. If it starts creeping up without a corresponding rise in job revenue, you're likely losing materials to waste, pilferage, or jobs where materials costs weren't quoted accurately. I've seen businesses where this number was off by 8–10 percentage points compared to what the financials suggested at settlement — because the previous owner had been absorbing overruns personally rather than charging them back to jobs.
Customer retention rate
For businesses with repeat customers — maintenance contracts, annual servicing, regular commercial clients — what percentage of customers from last year are still buying this year? A healthy trades business with commercial clients should be retaining above 75% year-on-year. Residential reactive work is harder to measure this way, but you can track return customers as a proportion of new bookings.
Review volume and rating
Not glamorous, but Google reviews affect your quoting conversion rate more than most owners realise. Track your review count and average rating monthly. Set a threshold — say, if average drops below 4.4 stars, that triggers an investigation. New owners often inherit a rating that's either much better or much worse than what the business actually deserves, so this is worth watching as you settle in.
How to actually track this stuff without spending your life in spreadsheets
Most Australian trades businesses run on job management software — ServiceM8, Tradify, simPRO, or similar. If the previous owner had one of these set up properly, your KPI data is mostly already there. If they were running off whiteboards and phone calls (it happens, more than you'd think), you'll need to migrate before you can measure anything.
A full walkthrough of what to look for and how to evaluate these platforms is in the job management software review. The short version: pick a platform that lets you create job-level reports so you can pull gross margin by job type and by technician — those two cuts alone will tell you most of what you need to know in the first 90 days.
For accounting, Xero connects to most job management platforms and gives you the financial view — debtors, cash, margins — in a format your accountant can actually work with. Set up the integration in week one and get the dashboard visible on your phone. You want to check it the way you check the weather.
When to review, and who to share the numbers with
Weekly for the first 90 days: job gross margin, conversion rate, debtors, cash. These change fast and you want to catch problems early.
Monthly after that: all five core metrics plus labour efficiency and customer retention.
Quarterly: a proper review with your accountant — benchmarking your numbers against industry norms and looking at trends. A good accountant who works with trades businesses will have comparisons for your industry and region. If yours doesn't, that's useful information too (about your accountant).
Share the relevant numbers with your operations manager or team leader if you have one. Not everything — just the metrics that relate to their work. Labour efficiency is useful for a team leader to see. Your cash position isn't. Trades businesses run on people who take pride in doing good work; giving them visibility into the numbers that measure that tends to improve performance, in my experience, without any additional management overhead.
What "normal" looks like — and when to worry
Numbers by themselves are just numbers. What matters is the trend and the context.
If your job gross margin drops 5 points in a single month, that's worth investigating before assuming it's a problem — it might be a one-off expensive job, a new service line you're still figuring out how to quote, or materials prices moving. But if it drops 5 points for three months in a row, something structural is changing and you need to know what it is.
A broker told me once about a trades business that looked great at settlement — solid margin, strong revenue, happy customers — but the new owner noticed the quoting conversion rate dropped from 58% to 38% in the first three months. Nobody had done anything wrong. The previous owner had been in the market for 20 years and got referrals from architects and project managers by reputation alone. New owner, same business name, but the referral network needed rebuilding. Knowing that early meant they could go fix it, rather than wondering for another six months why revenue was shrinking.
The first 90 days after buying a business covers the non-financial side of this period — staff, customers, processes. The KPIs are what help you know whether that work is translating into business performance.
Setting up your KPI tracking: the practical steps
- Get your job management software generating job-level reports (if it's not already)
- Connect your accounting software and confirm your chart of accounts is set up for job costing
- Pull the last 12 months of data if you can — it gives you a baseline to compare against
- Build a simple weekly dashboard: five numbers, one page, reviewed every Monday morning
- Grab the KPI checklist for new trades business owners — it covers the setup steps in detail including how to configure the common platforms
The first 90 days action plan has the broader context for where KPI tracking fits in the sequence of things you need to do as a new owner.
The KPI that people forget: your own time
How many hours are you working? As a new owner, almost certainly too many — that's expected. But track it anyway. One of the signs that a business is becoming an asset rather than a job is when your hours start coming down while revenue holds or grows. That shift usually happens somewhere between month six and month 18 for most owner-operated trades businesses in Australia, and it tends to happen faster if you've got the right systems in place from day one.
Documenting business processes is the foundation of that. You can't delegate a process that only exists in your head.
Frequently asked questions
What are the most important KPIs for a trades business in Australia?
Job gross margin, quoting conversion rate, average revenue per job, outstanding debtors, and cash on hand. Track these weekly in your first 90 days of ownership. Most of the data lives in your job management software.
What is a good job gross margin for a trades business?
Between 40% and 60% for most Australian trades. Specialist trades like electrical and plumbing tend toward the higher end. Labour-intensive, competitive trades like landscaping typically run between 35% and 50%.
How often should I review KPIs in a small trades business?
Weekly for the critical financial metrics in your first 90 days. Monthly after that, with a quarterly review alongside your accountant.
What KPI tells me if I'm underquoting?
A job gross margin consistently below 35%, combined with a quoting conversion rate above 75%, usually means you're winning work because you're the cheapest option — not because you're the best. That's a pricing problem, not a sales win.
Do I need special software to track KPIs in a trades business?
Not necessarily. A spreadsheet works fine if you're disciplined about updating it. Job management platforms like ServiceM8, Tradify, and simPRO generate most of this data automatically if set up correctly — which is why automating your quoting process and integrating with accounting software is worth doing early.
